Project Blue Book's most credible unresolved case. Socorro police officer Lonnie Zamora observed an egg-shaped craft on legs with two figures in white coveralls near a desert arroyo. The craft departed with a roar and flame, leaving behind four physical landing impressions and charred vegetation. FBI and Army investigators found the physical evidence compelling. Project Blue Book director Hynek called it the strongest physical evidence case in the entire Blue Book record.
On April 24, 1964, Socorro New Mexico police officer Lonnie Zamora was pursuing a speeder when he observed a flame and heard a roar. He drove toward the disturbance and saw an egg-shaped object on legs in a desert arroyo, with two small human-like figures in white coveralls standing nearby. As he approached on foot, the figures appeared to notice him and quickly re-entered the craft. The object emitted a loud roar and flame from its base and rose vertically, hovered briefly, and accelerated away horizontally at high speed with no further noise. Zamora was regarded as an exceptionally credible witness with a spotless record. Physical evidence at the site was extensive: four landing impressions in the soil consistent with a structured landing gear, charred brush and soil at the departure point, and no identifiable tire or human tracks near the marks. FBI agent Arthur Byrnes Jr. investigated and considered the physical evidence genuine. Project Blue Book director Dr. J. Allen Hynek described the Socorro case as the strongest physical evidence incident in Blue Book's entire 22-year record. No conventional explanation was ever officially assigned.

An ellipsoid bronze metallic object, 130–195 feet in length, materialized from a bright light and disappeared instantaneously. Rated among the most extraordinary events in the current indexed archive set.
Two experienced Eastern Airlines captains reported a cigar-shaped, double-decked object with a blazing exhaust that passed within 700 feet of their DC-3 at 700 mph over Montgomery, Alabama. Project Sign analysts concluded it was the 'most credible' UAP report of 1948 and drafted a classified estimate attributing it to extraterrestrial origin.
Two engineers observed a large egg-shaped object hovering silently over the Loch Raven Dam bridge. Their vehicle engine and lights failed during the approach. Upon the object's departure in a flash of white light, both men experienced sunburn-like symptoms and were examined by physicians. The USAF 438th Air Intelligence Service Squadron formally investigated and the case was classified 'Unknown' in Project Blue Book.
